Getting map extents using mode=map

[Ethan Alpert]

Extents are defined in the mapfile so you're not required to provide
extents in the URL.

Randy -

If you use mode=map you must SPECIFY the extents of the map when you
make the request.  You can't "retrieve" them since mode=map only returns
an image, but you can try to remember the extents you specified when you
made the request.  Unless you requested an area of a different shape
than your image, what you get is what you asked for.

Hi All,

I am using MapServer CGI, and have a questing regarding mode=map.   In
the
past I have used mode=browse, which allowed me to return information
such
as the map extents and scale via the template.   However, I now need to
switch to mode=map, and need to know if there is a way to retrieve the
extents and scale of the image produced.

Any suggestions?

Thanks,

Randy Page
